Qowaiv.Validation Test Tools

These test tools help to write meaningful tests and assert the state of a Result or Result<T>. The syntax is inspired by FluentAssertions.

These assertions could look like this:

Result.For(17).Should().BeValid()
    .WithoutMessages()
    .Value.Should().Be(17);

Where the chain after .Value exposes the value.

Other options for .IsValid() are:

Result.For(17).Shoud().BeValid()
    .WithMessage(ValidationMessage.Warn("Are you sure?"))
    .Value.Should().Be(17);

and

Result.For(17).Should().BeValid()
    .WithMessages(/* ... */)
    .Value.Should().Be(17);

Obviously, you can also check for invalidness:

Result.For(17).Should().BeInvalid();

In that case you do not have the option of .WithoutMessages(), obviously, as Result is defined to be invalid bases on containing at least one error message. Furthermore, it does not exposes the .Value as that is not accessible for an invalid result.

All (except for the .Value) is also applicable for the non-generic Result.

Validate with

There is also some syntactic sugar for testing validators on a model of choice:

var model = new MyModel();

Result<MyModel> result = model.ValidateWith(new ValidatorForMyModel());

And this result can be changed with the assertions described on top:

var model = new MyModel();
model.ValidateWith(new ValidatorForMyModel()).Should().BeValid();
